i don't know if he would get widespread support from mitch mcconnell and the leadership, but just a few who are maybe retiring, or leaving the senate. >> reporter: that's a great question. first and foremost they would have to be able to swallow the idea that they will effectively vote to raise taxes on the top 2% of americans which most republicans said they do not want to do because they think it is bad for the economy. to answer your question, it is probably the biggest sweetener for republicans and seen some moderate democrats by the way is the estate tax. the estate tax is in place right now at a relatively low threshold. it would go up big time at the end of the year. and that is something that is very important to a lot of republicans. that could be a sweetener. i think probably the best argument the democrats have for some of those republicans is that they don't want to be in the way or they don't want to be responsible in any way for every american's taxes going up, including most importantly the people who really, really need that money, people who just aren't the wealthiest i
